HI Neil,

I was asked to look over your nice poster. Below are some suggestions for you to consider.

Helen

“Extracting D0 Meson Tagged Jet Yield” Panel:

If I understood correctly you are missing mentioning the final step to extract the yield. Don’t you need to then integrate s_P_1 over the whole m_k,pi range and then scale by NEvents?

I also think it would be worth mentioning that you have T=2, because you assume a gaussian  for the signal and a pol3 for the background?

pT Spectrum Panel:

How do you conclude that MPI is important for low E charm yields? Your plot says MPI is off for LIDO and it agrees well with the data. I’m also not sure why you say low energy when you are contrasting peripheral and central events.

Does that fact that it agrees well with LIDO in peripheral data mean there’s lots of quenching even there? How does the peripheral data compare to scaled PYTHIA?

Fragmentation Function Panel:

Given you define z in both the figures you maybe don’t also need the definition in the red box.

Its not true this is the first z measurement of D0 in jet. See for example JHEP06(2023)133.pdf

The red highlighting of your last two bullet points is inconsistent. Suggest to highlight the hard/soft and suppressed/consistent with  1 parts of the sentences only.  No need to highlight D0 jet yield or central events.

You say the FF is only suppressed for central events, the mid-central suppression is essentially as significant (both really only hints) once all the uncertainties are combined.

D0 Radial Profile:

You never tell the audience what Delta(R) means

You mention that the radial profile is unfolded but don’t mention this for the FF, does that mean its not unfolded?

I suggest to move the comment about the LHC results to a sub bullet when you report what you see in the ratio, in this way your nice results are what the audience sees and thinks about first

You have two bullet that say your results are consistent with LIDO, you really only need one. Related to LIDO does it agree with the LHC results? i.e. does theory expect that this variable only becomes sensitive to diffusion effects at energies > RHIC?

Hi everyone, please find my poster contribution here. https://drupal.star.bnl.gov/STAR/system/files/QM2023_Poster_Diptanil_36x48_v1.pdf

I have put the most recent versions of the preliminary plots on the poster, please let me know if you have any suggestions/comments on the plots. The latest preliminary request version is available here: https://drupal.star.bnl.gov/STAR/system/files/PreliminaryRequest_QM_Aug20_2023_v3.pdf.

In addition, I added a raw D0 yield plot. Please let me know if I need to request a preliminary for that plot.

Thank you.
